Re: C5 2008 (X7 ?) Turbo Fault
I'm not surprised - I don't trust the ebay 'parts' system one bit - totally useless. But as long as they are quoting the correct part number that matches the OEM one - it should cover you, otherwise they are falsely advertising.

Re: C5 2008 (X7 ?) Turbo Fault
Yes, definitely the right part number. I've found a pattern one for under £20 but also need the banjos 0376 55 & 0376 56 60 and washers 0157 08 (x4)
ETA: Found a kit inclusive of those parts for £43 all in. https://www.ebay.co.uk/itm/PEUGEOT-CITR ... ctupt=true

Re: C5 2008 (X7 ?) Turbo Fault
Kit was delivered yesterday and pleased to note the pipe was manufactured by Mahle and the other parts were genuine PSA including the revised longer sleeved gauze filter.
Does anyone know how this "flexible" banjo fitting works, or rather how it can fail?
I can flex the pipe inside the banjo fitting by pushing sideways on it (as per diagram C) which is how the mech says it leaks.
According to Citroen fitting instructions, the pipe is centrally aligned to the banjo fitted with a 3 degree tolerance! Fitting it outside this tolerance may result in a leak and the fix is simply to re-align it properly. This makes me think a replacement maybe wasn't needed at all?

Re: C5 2008 (X7 ?) Turbo Fault
Here's an interesting video of a 1.6 Picasso of removing the turbo and bits Mike - shock of horrors what he found by the vanes!
He does come on tot turbo oil pipes though in several parts.

Re: C5 2008 (X7 ?) Turbo Fault
The theory I believe is oil starvation and the resultant excess spindle play allows the vanes to contact the housing, causing a stall. Over time, this loosens the nut and it comes off, free to wreck the compressor wheel. I'd imagine there were plenty of warning signs before it can get that bad.
But getting back to this oil feed pipe, the circlip (difficult buggers at the best of times) securing the actuator arm sits just behind the pipe with narrow access either side.
There's potential for straining this pipe when trying to remove or refit the circlip. Perhaps that was when the mech noticed oil seepage?

Re: C5 2008 (X7 ?) Turbo Fault
Garaged phoned to confirm turbo solenoid, diaphragm and oil pipe have all been replaced as asked, so popped round to settle up with them and enquire how the work went.
Aside from the bottom oil pipe bolt being a pig to get to causing them to stay overtime on Saturday, it all went well (and my pocket is much lighter for it).
He showed me the old oil pipe and the top connector (where the pipe floats inside the banjo fitting) where I could see it certainly had far more freeplay movement than the bottom one. He also told me he had initially tried to reset/straighten the original banjo/pipe position (as per the diagram posted above) and it instantly leaked. Interestingly, he also told me there was no filter gauze in the old pipe, both suggesting someone's been there before and perhaps not refitted the pipe correctly?
Also, the engine undertray was fitted with tie wraps (though I imagine they are quicker/easier for mechanics to undo/refit than the proper set of OE fasteners?).
As the car's not insured I left it with him to drop it back at close of business. He said he did take it for a test drive, says it seems to be boosting ok but didn't do any diagnostic code reading/clearing. When I can, I'll get another shorterm insurance cover to check the fault codes and assess if the original underboost fault has finally been fixed or not.

Re: C5 2008 (X7 ?) Turbo Fault
Sounds like you may be right about a previous bodge Mike. It just goes to show you never know what’s gone on before and all the subsequent grief sowmething like this can inflict down the line. I do hope this is the end if that issue and that she returns to life.

Think a call to the previous owner would maybe shed some light on the issue, but having owned it for best part of 8 years i can honestly say i have not even showed a spanner in its direction until i tried to fix the problems documented in this thread, and i have been totally honest with Mike and answered all of his questions.
That being said there is only 1 time the car has gone somewhere other than where any of my family cars go, and that was May of 2018.
Just goes to show you cannot trust anyone these days when buying a second hand car
Mike i am really pleased you may have gotten the old girl sorted, mainly for you as you took a risk, and a little bit for myself as in my head i still believe it is a good car in the right hands.

I should of clarified, but of course I was referring to ownership previous to you Colin - I'm sure the car had exemplary care in your ownership!

If only that was the case, i was lax on oil/filter changes etc, it just seemed to keep going, when an issue arose it was sent to be sorted, things like brakes were all done when required but i just let things slip as it never let me down in close to 8 years and now i do not have it i miss it
Lesson learnt, take care of it even when it seems okay, small things done regularly keep it running sweet, and it does not help when my son has an 10 plate 2.0hdi C5 sat in the driveway in the same colour
But every cloud has a silver lining, my daily driver is a Xantia 2.0 hdi

Re: C5 2008 (X7 ?) Turbo Fault
I was speculating on the cause of the pipe seal failure, not trying to point fingers.
The pipe's been replaced and the provided new parts have been fitted along with the previous doser/maf swap. I'm now itching to know if that's finally sorted the underboost issue so I can next look toward getting the cambelt replaced and a full service.

Re: C5 2008 (X7 ?) Turbo Fault
I think it's fixed.
Cleared codes and recorded air parameters for turbo behaviour.
Measured boost appears to very closely follow reference values now (better than my MKII even) and the underboost fault code has not returned after a 15mile run.

Re: C5 2008 (X7 ?) Turbo Fault
Good news Mike, well done for the perseverance. Could you do a post that summarises the changes that helped / cured, and the ones that were red herrings?
Again well done.

Re: C5 2008 (X7 ?) Turbo Fault
I know that Mike, just wanted to make it clear to those that may not know both of us as well as we know each other that you jumped in with both feet and eyes wide open
I am happier than you are right now
Yes i agree it would be nice to see what Mike and myself have done that did or did not help/affect the issues that arose from the original diagnosis being the Turbo at fault.
The other issue that prompted the diagnostic was the DPF warning and the service light being on.
Around town and bit of dual carriageway returned between 44-48 mpg, a daily 70 mile round trip mainly dual carriageway even with the faults returned 52 mpg so no pressure MikeGiveMeABreak wrote: ↑30 Jan 2019, 18:20 Excellent - now we're looking forward to seeing your new X7's MPG as compared to the MK II!
